Thank you, Jeff. Good morning, everyone and thank you for taking the time to join us. With me today on today's call is Dr. Nicholas Borys, Celsion's Chief Medical Officer, and Jeffrey Church, our Chief Financial Officer, from whom you just heard. As always, we are delighted to have the opportunity to update you on our progress and importantly, to answer your question. Seeing that our last conference call was less than six weeks ago and that we are just a few days away from our annual shareholder meeting, today's prepared remarks will be relatively brief and maybe a bit repetitive, but I hope that you will agree with me that some things, particularly good things like you will hear today are worth repeating. Before getting started, however, I want to remind you that we have a number of important proposals to be acted upon during the annual shareholder meeting on this coming Tuesday, May 16. The affirmative vote on each of these issues is recommended by your board of directors as they set the stage for the most important of future developments from your company. By this time next year we will be approaching full enrollment of our Phase III OPTIMA Study in primary liver cancer, also known as HCC or hepatocellular carcinoma. We are now likely 18 to 20 months from the first preplanned interim analysis of overall survival. Assuming positive data, this event will no doubt be transformative. In support of these objectives, a proxy was mailed to you -- the proxy that was mailed to you includes two very important enabling proposals for shareholders to consider. First is a proposal to authorize the board to effect a reverse split, ensuring that the company remains in compliance with NASDAQ listing requirements. The liquidity of our shares and our ability to raise capital will depend upon approval of this proposal by our shareholders. The second proposal authorizes the company to issue more than 20% of our unaffiliated shares in a financing transaction of up to $25 million, with authorization for a discount as conditions warrant. The objective of this one time authorization is to minimize, if not eliminate, the devastating small iterative financing to which the company has been recently limited. Shareholder support not only could get us to a more positive financing environment, it may well finance us properly the first data readout of the OPTIMA study. The proxy was mailed to shareholders in early April. If you have not received it, please call and call right away. You can find our number on our Web site at www.celsion.com. We will help you to quickly register your vote if you should call. One last time. Vote matters. It's important. If you haven't done so, please vote. On behalf of your board, I want you to know that your support is appreciated. Now with that public service announcement behind us, I want to focus my comments on our two very important product candidates, ThermoDox and GEN-1. And this maybe a bit repetitive, as I mentioned during our year-end earnings call, the fundamentals of Celsion are sound, no doubt are sound. From an operating perspective, it's my view that we have never been in a better position. I want to share some examples of why you should believe this is so. First, number one, operational risk associated with our Phase III OPTIMA study is virtually non-existent. This highly de-risked study of ThermoDox plus RFA in newly diagnosed HCC patients, which represents, as you know, the largest unmet medical need in oncology. This study is being conducted in an exceedingly professional and efficient manner. And all of the heavy lifting has been done, including the following. We have established unparalleled support from the medical establishment and are conducting the OPTIMA Study with a public backing from some of the most respected researchers and institutions in the liver cancer world. 15 regulatory agencies from across the globe in all the major HCC markets, have reviewed and approved the OPTIMA study protocol. We have clinical trial agreements with some 70 of the leading hospitals dedicated to liver cancer research, backed by hundreds of highly respected investigators worldwide. We have engaged internationally recognized world-class CROs, contract research organizations, and data management teams to ensure [GCP] [ph] and protocol compliance and high quality data analysis. We are enrolling patients on schedule at an excellent pace. But never satisfied, we are working always to do better. We have a proven and highly reliable supply chain with three contract manufacturing organizations. One in China, two in the United States, that’s three, registered and capable to produce ThermoDox, providing a cost structure that all but guarantees enviable gross margins regardless of the local economy, regardless of the country. So in summary, with minimal operation risk, we are now looking forward to study completion and data. If you believe our many analyses that support the OPTIMA study or if you have any confidence in the independent opinion of the National Institute of Health, then you should have to agree that there are chances of success with our OPTIMA study is as good as it gets in our industry. A second example that our fundamentals are sound is in the execution of the OVATION. This is a Phase I study evaluating our highly innovative gene mediated immunotherapy, GEN-I in newly diagnosed ovarian cancer patients. This study is all but complete. From it we now know almost with certainty that GEN-I has significant promise. There is no doubt that the production of therapeutic IL-12 in this patient population is dose related. We also see a clear relationship between dose and the activation of key elements of the immune system. More promising and importantly early clinical findings appear to tie this translational data to -- translational data tied to clinical finding. Our findings from the OVATION study will be presented by our lead investigator, Dr. Premal Thaker, Professor of Medicine at Washington University in St. Louis, at the 2017 ASCO annual meeting this coming June in this very difficult to treat patient population. An important Phase I study with a novel approach to harnessing a potent anti-cancer cytokine, IL-12 is all done door to door in less than two years for less than $2 million in total. I will give you a third example. It's the European DIGNITY study, a refractory breast cancer patient study of population where we have seen ThermoDox plus hypothermia provide results that have been nothing short of remarkable. The study has been teed up. All the administrative IRV contract and protocol training and review issues have been completed. Study is ready to go on five institutions in Europe and Israel, now just awaiting financing to initiate enrollment. The fourth examples is the work that we have done with our cost structure. The cost structure has been reengineered. Jeff Church will go over in some detail with you what that means financially. But we are operating with 30% fewer employees than just 18 months ago. 30% fewer employees than just 18 months ago. All-in future spending on average will be approximately $1.3 million per months. And that covers three clinical studies including a global Phase III pivotal trial, maintenance of two investigational products, not an insignificant task by any means, conducting trials in more than 75 clinical centers across 17 time zones in 17 countries. So I hope that you agree with me and our fundamentals are sound with very little operational risk in trial management, PMC or regulatory compliance. You can be confident that our studies are professionally and rigorously managed and we are addressing potential billion dollar market opportunities. And if we are right, these are the primary, liver cancer study OPTIMA, our ovarian cancer program demonstrates a meaningful clinical benefit. In our well controlled studies, we would expect global regulatory approval, rapid adoption and generous gross margin. I would like to go into a little bit more detail with regards to ThermoDox, Phase III OPTIMA study has passed the midway point, on a track to complete enrollment of 550 patients on around the end of the second quarter next year. Our target is newly diagnosed, primary liver cancer patients or HCC, hepatocellular carcinoma patients. We are evaluating the potential OS benefit of ThermoDox plus standardized RFA, as a first line combination treatment. The study is powered to show a 33% reduction in the risk for death. If achieved, ThermoDox will represent the only non-surgical curative option for HCC patients. That’s a single dose of ThermoDox plus RFA properly administered, being potentially curative. So it's being conducted in over 60 clinical sites in North America, Europe, China and Asia. A hypothesis for the OPTIMA study, I am continuing to say this is highly de-risked study, the hypothesis is supported with statistically significant sub-group data from or prior HEAT study. A 700 patient evaluation of ThermoDox in combination with radiofrequency ablation or RFA. Failing to meet is PFS endpoint, as progression free survival endpoint, the multiple analyses and findings from our preclinical studies have shown the RFA to be effective in larger lesions, a minimum heating timing threshold is required. This finding is consistent. With our understanding of the engineer design limitations of RFA and with ThermoDox's mechanism of action. This is understanding that has driven the design of, again, the highly de-risked OPTIMA study. The final data supporting the OPTIMA study was derived from a subgroup of patients with single lesion, was treated with RFAs standardized for greater than 45 minutes. In this large well bonded, well balanced subgroup of 285 patients, a group that we followed for over three years, received a treatment with a combination of ThermoDox and standardized RFA that’s greater than 45 minutes. Provided an average of 54% risk improvement and overall survival. The hazard ratio in this analysis is 0.65, with a p value of 0.02. Simply put, this translates into a greater than two year survival benefit from the ThermoDox arm over the optimized RFA group only. And after 80 months, the median overall survival for the ThermoDox group still had not been reached. Historically, median time to death in this population is around 36 months and 57 months in a comparable group from the HEAT study. The regulatory reaction for this analysis has been generally quite positive. No doubt, there will always be some concern with post-hoc analyses. But during the fourth quarter, for example, Dr. Borys and I discussed the supporting data in the OPTIMA study with regulatory agencies in China and Vietnam. We reported on these meetings and just want to review with the conclusions or the results from these meetings again with you. CFDA, the Chinese food and drug administration informed the company that conditioned on the strength of the data, if the Phase III OPTIMA study is successful, this trial could serve as the basis for a direct regulatory NDA filing in China without the need for prior approval in the U.S. or the European Union. Now this prior approval, known as CPP, which is currently required for foreign companies to file an NDA in China. So this allowance underscores the significance of our work as we interpret it. No doubt that will allow us to accelerate our commercial plans for China. Why is this important? Well, as you know, as we have said, China represents what is perhaps the most significant market opportunity for ThermoDox in the world, as approximately 50% of the 850,000 of more new cases diagnosed each year originate in China in this market. The future largest market for pharmaceuticals in the world. I have to say to you, I believe, I hope you agree the company is well positioned. And as I discussed on the year-end earnings call, last November, Dr. Borys and I also met with the Ministry of Health in Hanoi, Vietnam and I am fond of saying that that meeting occurred on a Sunday. That’s how interested they were in meeting with us. Based on the very positive meeting, we received regulatory approval to initiate five additional clinical sites in that country and record time. The clinical team, that was in November, our clinical team has already activated four sites. They are enrolling patients in a productive manner. The clinical team active expects to activate the fifth and final site in Vietnam in the next few weeks. Why is this important? Vietnam represents a significant market for ThermoDox for HCC incident rates are among the highest in the world. And the last point I want to make on OPTIMA and ThermoDox, and this is a key point. We have talked about this. The OPTIMA study continues to be supported by a growing body of peer reviewed research. And I will point to the national institutes of health, to conduct an independent analysis of the supporting data on their own. As for the data, we didn’t ask them to do this. They presented their findings during oral sessions at the RSNA conference in Chicago last December. But the NIH in their analysis, independently saw to retrospectively evaluate the co-relation between RFA burn time, that’s the dwell time, 45 minutes that we talk about. They evaluated that per tumor volume and compared to the clinical outcome in patients treated with ThermoDox as compared to patients treated without ThermoDox. Now their conclusion was both statistically significant and very straight forward and I quote from their presentation, "As you increase RFA burn time in patients treated with ThermoDox, overall survival improves. The same is NOT TRUE for patients treated with RFA alone." The NIH's independent assessment provides additional confirmatory support. I hope you agree, consistent with our own findings, indicating that use of RFA for more than 45 minutes in patients treated with ThermoDox in lesions of course larger than 3 cm, is our focus group, who are enrolling in our study. In these patients treated with RFA for more than 45 minutes with the addition of ThermoDox can impact favorably overall survival. In this presentation, as I have represented, what was a full house, very large presentation room. My guess is well over 500 attendees. The NIH concluded its discussion with very clear and convincing support for the OPTIMA study. So this independent analysis strengthens our confidence as I believe it should yours. Now as in a sight, in talking about the NIH, they continue to evaluate many potential applications for ThermoDox. I think their excitement with this very unique and novel means of delivering known chemo-therapeutics in the case of ThermoDox, doxorubicin, I think their excitement is something like I have never seen. They have recently published preclinical results of ThermoDox for the treatment of bladder cancer in the International Journal of Hypothermia. The article describes the results of in vivo pig studies to evaluate ThermoDox in combination with hypothermia for targeted drug delivery to the bladder walls as a potential treatment for bladder cancer. A very underserved population. Doxorubicin accumulation and distribution within the bladder wall with ThermoDox has a function, plus mild bladder hypothermia was achieved a concentration ten times higher than with free intravenous doxorubicin combined with mild hyperthermia. So the mechanism as have been talking about for years now is clear that ThermoDox administered systemically, intravenously, warm with the mild hypothermic to the bladder increases the drug concentration in the wall of the bladder. The muscle wall, the tissue of the bladder ten times greater than free doxorubicin. With approximately 90,000 instruments in the U.S., this is an important unserved need and the data that we are looking at could very well provide a basis for clinical program of ThermoDox and bladder cancer. More to come on that issue. Dr. Borys Nick and I are meeting with key opinion leaders at the [ADA] [ph] conference this weekend to discuss the potential for clinical research. And by the way the meeting that these KOL, key opinion leaders, in bladder cancer research have [indiscernible] asked us to conduct. Based on their research, the NIH is no doubt, as I said earlier, excited with ThermoDox in addition to HCC bladder and some work they have done on recurring chest wall breast cancer. The NIH is now conducting a phase II study in pediatric solid tumor patients at the children's hospital. Pretty exciting story. So now, let met turn to GEN-1, our immuno-oncology candidate developed on our TheraPlas technology platform. As you may recall, Gen-1 is a gene-mediated immuno-therapeutic which recruits the entirety of the immune system to fight malignancy. Gen-1 active agent is a DNA plasmid that’s coded for the cytokine interleukin 12, or IL-12. The IL-12 plasmid is incorporated into this TheraPlas platform. It's a non-viral nanoparticle delivery vector. When administered locally into a body cavity like the peritoneum of the bladder or even a cavity that's been created by the surgical removal of a tumor mass, these nanoparticles invade the surrounding cells and take over the metabolic machinery turning each of these cells into a mini factories for the sustained local production of IL-12. It's a protein, [indiscernible] inflammatory protein, well know to recruit the immune system to fight cancer. Our first indication for GEN-1 is ovarian cancer, as we have talked about. For patients newly diagnosed with this malignancy there is less than a 45% chance of surviving five years. One of the major reasons is that diagnosis is made when patients are symptomatic, at stage three or more, when the cancer is advanced. In trials of this patient population conducted by the GOG, prior to our involvement, the GOG was handling all the clinical trials, it's the gynecologic oncology group. They are a cooperative funded by the NIH. So in these trials when GEN-1 is used either as a monotherapy or in combination with chemotherapy, the findings appear to us to be quite promising. So much so that we continue the research. Celsion's first trial in this indication, we called the OVATION study. This is fully enrolled with the last patients currently being evaluated for treatment. Initial clinical findings and translational data will be presented in June at ASCO. We are also following these patients for an important regulatory endpoint of progression free survival. OVATION was initiated in the fourth quarter of 2015. So it’s less than two years ago. It's a Phase I study in newly diagnosed stage three and four over cancer patients, late stage patients. Individuals who unfortunately have large tumor mass in the abdomen. So these patients present with heavy disease burden prior to debulking surgery which is indicated they are treated with up to three cycles of carboplatin and taxane, the goal of which is to improve the surgical outcome by shrinking these tumors and drying up the ascites. So in this population, to this regimen we are adding eight weekly cycles of GEN-1, which is then followed by the interval of debulking surgery. I want to review quickly. We issued a number of press releases here. So I will review quickly a summary of the data that we have issued via press releases during 2016 and 2017. So with this I will remind of the first 13 patients dosed, we saw 100% disease control rate and a 92% objective response as measured by RECIST. All 13 patients had resections of their tumors, as reported by the surgeons. 54%, 7 patients had an R0 resection. That’s a margin negative resection. Four patients had an R1 resection and two patients had an R2 resection. I provide the accounts from the surgeons whom we talk to quite regularly. They are highly optimistic with better than expected outcomes in these patients, again with advanced disease. From the pathology reports of the 12 surgically treated protocol, one patient demonstrated a pathologic complete response, very rare in this indication. So the surgeon found no evidence of cancer and in the pathology it appeared that there was no living cancer tissue. One patient demonstrated a pathologic complete response, six demonstrated a micro pathological response and five demonstrated a macro response. These numbers are small but better outcomes than what had been anticipated based on the historical understanding. The patients at this stage are small numbers but again quite impressive based on what was expected or anticipated from the surgeons and from the literature. None of the patients lapsed. All 11 patients who completed treatment follow up experienced a dramatic, that’s a greater than 90% reduction drop in the cancer antigen protein 125. CA-125, as we have talked about, is present in higher concentration in ovarian cancer cells than in healthy cells. A 50% reduction is considered meaningful, clinically meaningful. In all of our patients, greater than 90% drop. So we have also reported preliminary translation data from the from the OVATION study focusing primarily on positive treatment of related changes in the immune environment and tumor tissue and in the tumor ascites that accompanies tumor mass. These data demonstrate clearly dose dependent increases NIL-12] [ph] and interferon and corresponding decreases in VEGF. VEGF as you know is part and parcel responsible for advancing vascular growth that support tumor expansion. So a decrease in VEGF can be meaningful, [indiscernible] growth that supports tumors. We also saw in increase in the tumor tissue of tumor fighting T cells and a corresponding decrease in Treg cells. These Treg cells are responsible for suppressing the immune system. It's just a quick summary of GEN-1 and ovarian cancer patients from our study. It is biologically active, appears to have an immuno-stimulatory effect in the perinephric fluid is a does dependent manner. It promotes a protein cell activity in tumor tissue taking the brakes of the immune system by decreasing the Treg cell. All in all, I would say from the Phase I study, we are pretty impressive. So the next step in our clinical strategy assuming -- and this is involving seeing such positive data set coming out of this study, we may evolve our thinking with regards to the next steps. But as of now, assuming we have a dose from the OVATION study, we will remain on track for an IND submission for a Phase I/II clinical trial, combining GEN-1 with the Avastin and Doxil in the recurrent population of ovarian cancer patients. So with that, now I will turn the call over to Jeff who will review our financial results. Jeff?
